View Full Version : Discussion: Evidence for Planets Around Vega

2003-Dec-01, 08:55 PM
SUMMARY: Astronomers from the Particle Physics and Astronomy Research Council believe they've discovered a planetary system around Vega, one of the brightest stars in the sky. Not only that, the star system seems remarkably similar to our own Solar System. So far, they've found evidence for a Neptune-sized planet in the same orbit as our own Neptune. This means there could be smaller, rocky planets closer in to the star.

How long before they find the network of inter-galactic wormholes??? :D

[FONTThere could be rocky Planets just because there is evidence of one Neptune sized planet?? There could be the Star ship Enterprise orbiting the star with that degree of evidence. What do you think?=Arial]

[I thought no planets were around A stars? Look at Sirius.

Apparently not the case, although I suspect that any small planets with rocky cores orbiting at the distance of Earth/Mars/asteroid belt would be so highly irradiated by an A0 star like Vega that they'd be much like Mercury, and probably in gravitational harmonic rotation periods as well.

Very exciting news although I doubt there would be life there considering how much larger and brighter the star is.

Very exciting .... but not surprising. The sheer magnitude of star systems all governed by a similar caldron of natrural forces ... begs discovery of many additional planetary systems. Mathemtaical odds ... despite lacking proof of extra-terrestrial life ... all but screams at its liklihood.
